In this case, the toilet device 1 may be provided with an appropriate operation unit or the like. Various other modifications are possible as the supply mode of the sterilizing liquid.

The sterilizing liquid supply device 20 according to the present embodiment and the toilet device 1 including the sterilizing liquid supply device can effectively spray the sterilizing liquid on the inner surface of the bowl portion 10 as a sterilization target by using the above-described configuration. it can.
That is, it is arranged so as to face the lower side of the discharge port 25 with a gap so that the sterilizing liquid discharged from the discharge pipe 24 provided with the discharge port 25 so as to open downward is applied. It is set as the structure which provided the watering part 28 which has the flat surface-like watering surface part 29 which faces the side. In addition, a support portion 27 that supports the water sprinkling portion 28 on the outer side of the discharge pipe 24 is provided. Accordingly, the sterilizing liquid discharged from the discharge port 25 can collide with the water spraying surface portion 29 and can be sprayed over the entire circumference so as to be scattered in the surface area direction of the water spraying surface portion 29. Moreover, compared with what inserted the other member in the discharge pipe, the water sprinkling part 28 and the support part 27 are hard to become a cause of pressure loss, can suppress the fall of the flow velocity, and the inside of the bowl part 10 inner surface as sterilization object Water can be effectively sprayed over a wide area. Further, since the sterilizing liquid colliding with the water spray surface portion 29 is scattered in the form of water droplets, for example, in an aspect in which a mist-shaped sterilizing liquid is sprayed, ozone water or the like whose concentration tends to decrease during spraying is used as the sterilizing liquid. Even in this case, a decrease in density can be suppressed.

Moreover, in this embodiment, it is set as the structure which supplies the sterilizing liquid supply apparatus 20 toward the inner surface of the bowl part 10 as the sterilization object enclosed by the surrounding wall part. Therefore, the sterilizing liquid that collides with the water spraying surface portion 29 and scatters in the surface area direction can be adhered over substantially the entire circumference of the inner peripheral surface portion of the bowl portion 10.
In the present embodiment, the discharge pipe 24 and the water sprinkling portion 28 are arranged so as to be positioned on the peripheral wall portion of the bowl portion 10 in plan view. Therefore, for example, the disinfecting liquid supply line 23 is less noticeable or easier to pipe than the discharge pipe 24 and the water sprinkling section 28 provided in a plan view so as to be positioned at the center of the bowl section 10. Become.

  Further, in the present embodiment, both or one of the surface orthogonal to the discharge direction from the discharge port 25 of the discharge pipe 24 and the water spray surface portion 29 of the water spray portion 28 is inclined so as to face the peripheral wall portion side facing the arrangement location. It is in the shape. Accordingly, the discharge direction from the discharge port 25 with respect to the water spray surface portion 29 is not the normal line direction, and a large amount of the sterilizing liquid discharged to the water spray surface portion 29 is scattered on the side of the bowl portion 10 facing the disposition location. Direction. Thereby, a disinfection liquid can be effectively sprinkled toward the opposing surrounding wall part side which is a side far from the location where these discharge pipes 24 and the water sprinkling part 28 are arrange | positioned. Instead of such a mode, both the surface orthogonal to the discharge direction from the discharge port 25 of the discharge pipe 24 and the water spray surface portion 29 of the water spray portion 28 may be formed in a horizontal plane.

  Moreover, in this embodiment, it is set as the structure which provided the discharge port 25 of the discharge pipe 24 so that a disinfection liquid may contact | win the surrounding wall part side site | part facing the arrangement | positioning location in the watering surface part 29 of the watering part 28. FIG. Therefore, the range of contact with the water spraying surface 29 of the sterilizing liquid that is discharged to the water spraying surface portion 29 and splashes in the surface area (diameter) direction from the peripheral edge of the water spraying surface portion 29 along the surface region direction of the water spraying surface portion 29 is circumferential. It becomes small in the site | part of the site | part side which opposes an arrangement | positioning location. Thereby, the fall of the flow rate of the sterilizing liquid scattered through the said site | part can be suppressed effectively, and the surrounding peripheral wall part side which becomes a side far from the location where these discharge pipes 24 and the water sprinkling part 28 were arrange | positioned. The sterilizing liquid can be effectively sprinkled toward the water. In addition, it is good also as an aspect which replaced with such an aspect and provided the discharge port 25 of the discharge pipe 24 so that a disinfection liquid may contact | win the approximate center part of the water spraying surface part 29. FIG.

  Moreover, in this embodiment, the support part 27 is made into the structure which supports the water sprinkling part 28 from the downward side. Therefore, for example, compared to the case where the support portion 27 is connected to the peripheral portion of the water spray surface portion 29, it is possible to suppress the sterilizing liquid that has collided with the water spray surface portion 29 from flowing along the support portion 27. Water can be sprayed more effectively in the surface area direction of the water spray surface portion 29. In addition, it is good also as a structure which replaces such an aspect and supports the water sprinkling part 28 from the side. In this case, it is good also as a structure which connected the support part 27 to the outer peripheral part of the lower end side of the water sprinkling part 28. FIG.

  In the present embodiment, the support portion 27 is supported by the discharge pipe 24. Therefore, for example, compared with the case where the support part 27 is supported on the bowl part 10 or other part of the toilet body as a sterilization target, the positional deviation at the time of installation of the discharge port 25 and the water spray surface part 29 of the discharge pipe 24, etc. Can be made difficult, and effective watering becomes possible. Instead of such a mode, the support part 27 may be supported by the bowl part 10 or other parts of the toilet body.

  Moreover, in this embodiment, the watering surface part 29 of the watering part 28 is made into substantially circular shape seeing in the direction perpendicular | vertical to a surface. Therefore, as compared with the water spraying surface portion 29 having a polygonal shape, the sterilizing liquid splashed from the peripheral portion of the watering surface portion 29 is likely to adhere to the inner surface of the bowl portion 10 as the object of sterilization in a generally annular or substantially U shape. Thus, the peripheral wall portion to be sterilized is suitable for the one having a substantially circular shape or a substantially elliptical shape in plan view. In addition, the shape seen in the direction perpendicular | vertical to the surface of the water spraying surface part 29 of the water spraying part 28 may be made into a substantially elliptical shape instead of the aspect made into the substantially circular shape, Furthermore, it is good also as a substantially polygonal shape. In this case, the water sprinkling part 28 may be formed in a substantially elliptical column shape according to the shape of the watering surface part 29, a substantially polygonal columnar shape, or the like. Further, in the present embodiment, an example in which the water sprinkling portion 28 is substantially columnar is shown, but it may be a relatively thin substantially plate-like shape.

  Moreover, in this embodiment, the discharge pipe 24 and the water sprinkling part 28 are arranged so as to be located inside the inner peripheral wall on the back side in the toilet depth direction of the opening peripheral part as the peripheral wall part of the bowl part 10 as a sterilization target. However, it is good also as an aspect provided in the toilet depth direction near side, the toilet width direction one side, etc. Moreover, as an aspect which arrange | positions these discharge pipes 24 and the water sprinkling part 28 so that it may be located in the surrounding wall part of sterilization object by planar view, it is not restricted to the opening peripheral part of the bowl part 10, For example, the toilet lid 5 and the toilet seat It is good also as an aspect provided in the back surface of 4. Further, instead of the mode in which the discharge pipe 24 and the water spraying portion 28 are arranged so as to be positioned on the peripheral wall portion to be sterilized in a plan view, the central portion to be sterilized in a plan view is used. It is good also as what is arranged so that it may be located. For example, the discharge pipe 24 and the water sprinkling part 28 may be arranged on the back surface of the toilet lid 5 so as to be located in the center part of the bowl part 10 in a plan view. Various other modifications are possible for the locations where the discharge pipe 24 and the water sprinkling section 28 are disposed.

Moreover, although the example which made the trap part 16 of the toilet device 1 the thing of a turn trap type is shown in this embodiment, it is not restricted to such an aspect. For example, you may make it employ | adopt other drainage mechanisms, such as a siphon set type, a siphon type, a siphon vortex type, a neo-vortex type, and a wash-off type. In this case, as described above, when the water level is lowered, an appropriate water level variable mechanism that can maintain the water level of the bowl portion 10 at the low water level LV2 lower than the accumulated water level LV1 may be provided. Good.
In the present embodiment, the toilet device 1 is a sitting-type toilet device, but may be a Japanese-style toilet device, a urinal or the like.
